In the universal seesaw mass-matrix model, which is a promising model for the unified description of the quark and lepton mass matrices, the behaviors of the gauge coupling constants and intermediate energy scales in the model are investigated in relation to the neutrino-mass generation scenarios. The unification of the gauge coupling constants in the framework of the non-SUSY model is possible if the SO(10) symmetry is broken via Pati-Salam-type symmetries.
